Application filed December 4, 1913. Serial No. 804,754;

To all 'whom t may concern.' l

Beit known .that I, CHARLES W. Hirschau,

a citizen of the United States, residing at Veston, county of Middlesex, State of Massachusetts, have invented an Improvement in Processes of and Apparatus for Handling Yarn, of which the .following description, in

connection with the accompanying drawing,

is a. specification, like characters on the drawing representing like parts.

This invention relates to processof and apparatus for handling yarn preparatory to its 'being woven into cloth or made into twine.

In the textile industry it is now the common practice to subject the yarn to a plurality of operations preparatory to weaving it into cloth or making itinto twine, such, for instance, as spinning, twisting, spooling, doubling, winding and balling, and these operations are carried on on different ma-l chines so that the lcarrying out of these various operations necessitates the repeated transfer of the yarn mass from one machine .25 to another.v

yarn mass from one machine is commonly termed doling, while the operation of placing the yarn massjin the next machine for the .next operation is commonly termed creeling ing which are necessary in transferring the yarn from one machine to another consume a considerable time and also involve a large amount of labor, all of which is an important factor in the final expenselof producing the yarn. l

It is the object of my inventibn to provide a novel process of and appar; tus for handling yarn by which the time a jd expense incident to the operations of doijng and oreeling as now -carried on are very largely eliminated, th'us enabling me to produce :i yarn ata greatly decreased cdst from that now in vogue.

In carrying out my means whereby the two successive operations are performed simultaneously in one machine, the construction being such that the yarn is delivered from each operation directly into the yarn receiver from which it is drawn for the next si'icceeding operation, thus obviating any hand labor in effecting a transfer of the yarn mass from one machine or mechanism to another. With this arrangement it is possible to pass thc,

yarn from one operation to the other con- The operation of removing the t The repeated ycreeling and dotiyarn.

invention I provide the tinuously withoutl the usual doiiing and' creeling processes, these being automatically taken care of in the treatment of the yarn.

. I find that my invention. is particularly advantageous when used in connection with winding and twisting apparatus, such. as shown in my Patents No. 795,981 and No. 795,982, both dated August l, 1905,' and in my co-pendii'ig application Se. No. 8045,753A filed December 4, 1913, and therefore I have elected to illustrate my invention herein as it would be used in connection with appa@ ratus of this general type. I desire to state, however, that the invention is not limited in its use to spinning and twisting apparatusof the general type referred to in my vsaid patents and application.

In the accompanying drawings I have shown some selected embodiments ofthe invention from which .the principle thereoft will be readily understood, and Figures l, to 5 inclusive are diagrammatic views illus-` trating different ways of carrying out my methods; I? ig. (i is a vertical sectional View through an apparatus which includes a. winding -and twisting device of the type shown in said co-pending application; Fig. 7 is a front view of an apparatus ksuch as shown in Fig. l; Fig. 8 is a detail showing the head used during the doi'ling of the Before entering into a description of present invention I will first refer brielyv` to the yarn receiver which I have herein illustrated and ,which is set forth more pending application. This yarn receiver comprises a rotary yarn holderl, mounted on a vertical shaft 2 by which it is rotated,

which the yar'n mass within the yarn holder l is a extends down through the shaft 2 and is adapted to receive either a winding head 7, as seen in Fig. 6 that is constructed to lay yarn on the yarn support in transverse layers, or a pressure head 8, as seen in Fig.- S, which is used when the yarn is being doiied or withdrawn from the yarn receiver. The spindle 5 .and shaft. 2 carrying the yarn holder are rotated at different relative speeds by means of gears 9 and l0 which mesh with gears ll and 12 on the shaft 2 and spindle o, respectively,

with its means for1 twisting and winding the yarn therein I at length in my said cop-,i`

Y

When [my present invention is 'carried out in connection with a var'n rreceiver of mit;

type, I proposetoinse such :i Yarn receiver" for receiving the yarn :i inthe spinning' 'or twisting @pei-ation and un to. use the. saine, yarn recent-r is the cree? for the subsequent ufindi'ng` spoolinfg or d.i:hlineoperations, rnd ll also propose to gufi-' le a innchine so\ constructed that th. ser i ive, .'njlot'utions of windiiiif; pooling thuhli etc., can he carried ont tl reon sim:dnriwuslv. Vv'ith my inv ei vsive operations are i `-:ri v rrned in the .same machine and the yarn is delivered from mach' operation direed)P into' tl o yarn recciiwi-r tri-:n which it is drawn lr il. est hij; operation, so that ni, inannal lah. pin-ed in re?I l. chine which te :is creeling) :ind novided' Mij for the next succeeding operation. The step, therefore, ot ldelivering the yarn into n yarn receiver tor one operation constltutes the step' of supplying yarn to a yarn receiver for the nest succeeding operation, and since 73,

hoth ope -ations are carried ont'in the same machine` a saving in labor is thereby etli'ected.

In Fig. 1l I have shown diagrammatically how my invention would be applied to they douhlinf twistingr and s ioolin(r or windin it) is 'princesses ywhich consistin tav'ing a plurality of strands from different sources of supply and twisting yor doubling themtogether sindY `.vinding them, onto it yarirreccivernnd then transferring the twisted or so doubled strand from the yarn receiver onto a. spool` or reel. As heretofore practised, his yoperation of doubling and nvincling ,has necessitated the use of tvvo different mn.-

':hines, 1n one of which the various strands 35 a re doubled or twisted together, and then wound onto, a bohbin, and-in the other-'of which the yarn is wound from thebohbin` o'nto the rcel or spool. The usefof Such two.j

machines has, of course necessitated the 9o transfer ot' the yarn from one tothe other.

In applying my invention to this process ot' doubling, twisting and spo'olingLI pr'oposeffto provide :t machine Whichfncludes :i

pluralitgy of yarn receivers 21,' eaehpreer- 95 nhl;r ot thetype shovvn in Figs. 6, Tand 8,

ach yarn receiver having therein :L yarn mass which furnishes one of the strands 22 of the doubled strand. Each of these yarn` receivers ivill he provided with a. presser plate S, as shown in F ig. 8, which simply rests on the yarn mass and holds it in place :is it is withdrawn through thefhend 1S at the upper end of the holder 1.. The strands 22 ot yarn from the various yarn receivers 105 urir fed to a twisting and winding device 23 which may he similar to that shown in. Fig. 6 and which coxnprises a, yarn holderwith its yarnsupport-and a. winding head within the yarn holder adapted totwist the varn Vdelivered thereto sind to build up a yarn mass in the yarn holder.` As the yarn mass delivereil'to the yarn receiver or winding,r nl'iparzitus 23 the various strands are twisted together, as will he ohvious. The dovice also comprises another yarn receiver 2l' similar to the yarn receiver 23 except that `inst-cadet having the winding head 7 therein it is' provided with a presser plate The `vernis taken from this yarn receiver 2l 120 and delivered to the spool or reel '25. ln the operation of 'the mechanism illustrated dixtgrail'nlnaticnllv in Fig. l7 the strands 22 ot v airn villhey taken from the yarn receivers 21, tivisted together, und delivered to the `yarn"receiver 237 while the twisted -and doubled strand .in the, yarn receiver 2l is transferred to the reel 25. When the. vnrn receiver is Aillled :md the yarn receivers 21 and 24C are empty, then fresh filled ,yarn 130 receivers 21 are substituted for those which have been emptied and the winding head 7 1n the yarn receiver 23 will be exchanged for the presser plate 8 in the yarn receiver 24C,

and the strands of yarn from the lilled yarn receivers 2l will be yfed into the empty yarn receiver 24 and Wound therein, while the doubled strand in the -filled yarn receiver 23 will be fed to the reel 25, as shown by dotted lines' in F ig. l. With this arrangement the yarn receivers 23 and y2st are interchangeably usedand the filling of the yarn receiver 23 is carried on simultaneously with the emptying of the yarn receiver 24 and vice versa.

In carrying out the above operations l propose to so drive the yarn receiver 23 that it will put into the doubled strand about one-halfthe required amount oi twist and then when said strand is taken from said yarn receiver to be wound onto the reel 25, the yarn receiver is-rot'ated as the doubled strand is ,withdrawn therefrom, thereby putting into the @rand the other half of the desired twist between the yarn receiver and' the reel. The advantage of this is that the doubled yarn can be deliveredinto the yarn receiver 23 at a much greater speedthan if it were necessary to put the entire twist into the doubledv strand between the yarn receivers 2li and 23 or 24. YWith this arrangement the yarn receivers 23 and 24 act alternately as the-creels for the reel 25, and the dolling and creeling operations are carried on automatically and continuously and without the necessity of any labor.

In Figs. 2 and 3 l have shown an arrangement by which the operations of spinning, l

and spool ing can be carried out continuously in a single machine. These figures are dia.- grammatic entirely and are not intended to show details of construction. The machines shown in said figures comprise a frame of any suitable length which is made up in sections, each alternate section comprising a plurality of spools or ree-ls 26 and the other sections each having a plurality of pairs of spinning or drawing rolls 27. n These sections are shown as alternately arranged and each section has spools and six pairs of drawingrolls, although the number is not essential. Associated with the trame thus constituted is a plurality of sets of yarn receivers of the type above referred to. These yarn receivers are conveniciuly :nounted on a frame 28, andthis trainieand the partota the inachine carrying the reels 2'6- and drawing rolls 27 are movable relative lo cach other, so that they can be shifted relative tocar-li 'other iu a. direction longitudiuallv ci the machine. This may be mffoniplislwd by making either part movable. ln. the dravfin the trame carrying the rolls 2 s is movably mounted on the 'frame The Yarn. receivers are. arranged in ,s there being one set for each section of the machine, and in the illustrated embodiment of the invention there are six yarn receivers in each set. The

alternate sets of yarn receivers are designated 29 andthe other sets by 30. As shown with the emptying of the yarn receivers 29,I

and when the yarn receivers 30 are lilled and the yarn receiversl 29 are empty, then the carrier 28 and the spools and drawing rolls are shifted longitudinally relative to each other into the position shown in Fig. 3 thereby to bring the filled yarnreceivers 30 opposite the spools 26 and the empty yarn receivers 29 opposite the drawing rolls 27. The machine will be built with one eXtra set 'of spools or reels 26, there being a set at each end of the machine, asfshown in the drawings. This arrangement is adopted so that all of the yarn receivers may be utilized at all times. It will be understood, of course, that when the yarn in the receivers 29 has been transferred to the reels 26, said reels will be removed and empty reels will be substituted in their place; vWith 'this construction the emptying of the yarn receivers which are filled from the drawing rolls is carried 0n continuously and automatically in the operation of winding the yarn onthe spools 26 and simultaneously with the filling of the other yarn Ifeceivers,' and the filling of said other yarn-i: receivers is performed automatically and simultaheously -With the spinning operation. ,There is no labor nor time Spentz `in removing the yarn receiversfrom one machine and placing them in another machine for a dierent operation, the only labor nec essary at the end of any run being to change the spools 26, to shift the relative position of the carrier 28 and spools and drawing rolls, and to exchange the Winding heads 7 and spindle 5 in the yarn receivers 30 for the presser plates in the yarn receivers 29 and vice versa.

ln Figs. 4: and 5 I have shown diagramniatically a machine adapted for spinning, twisting and doul'iling and winding, and' arranged so that all of these operations are carried out simultaneously and without transferring the yarn from one machine to another. ln these figures 27 indicate drawing or spinning rolls and 30 designate a of yarn receivers adapted to receive the yarn from the drawing rolls. 29 designate another of yarn receivers similar to the yarn receivers 30, and 31 and 32 designate other yarn 'receivers larger than the yarn receivers 29 and 30 and adapted to receive doubled yarn. from the latter receivers. 33 designate spools or reels on which the yarn is finally wound. All of these parts can be conveniently mounted on a single frame and form part of the same machine.

ln the operation of the. machine the yarn receivers 2 are supposed to have been previously filled with spun yarn while the yarn receivers 30 are empty. The yarn receivers 32 have been filled with doubled yarn while the yarn receivers 3l are empty. The roving or ends from the' drawing rolls 27 are fed` rolls 27 are shifted laterally into position to deliver yarn to the yarn receivers Q9, the winding heads T in the yarnrcceivers 30 and 8l are exchanged for the presser 'plates in the yarn receivers Q9, 32, the ends from the filledy yarn receivers 30 are fed into the empty yarn'receivers 32, whilethe-donbled ends from the yarn receivers B1 are fed to the reels 33, all as shown in Fig. 5. The operation is then continued until the yarn receivers Q9 and 32 are filled arid the yarn receivers 3l and 30 are empty. at. which time the change is made back to they arrangement shown in Fi g. 4. Y 4

In all of the above operations I propose to place approximately one-half the twist in the "arn while itis being delivered to 'and laid in onev of the yarn reeeilversand then to rotate the yarn receiver as the yarn is taken out therefrom for the 'second operation, thereby to put into the tyyarn' theV rest of the desired twist. For ins ance, in Figs. 2 and 3 about one-half the twist desired will be put into the yarn between the drawing rolls 27 and the yarn receivers| 29 or 30, and then the other half of the twist will lbe put into the yarn between said yarn receivers and the spools QG. This can be readily accomplished by merely rotating the varn receivers as the yarn 1s being doffed therefrom,

the rotating of the yarn receivers" giving the additional twist to the yarn. Similarly in Figs. 4 and 5 approiimately/hal'n the twist vmay be put into the yarn as it is 'lvlivered to the yarn receivers 31 or 32 and the other half of the twist put into the vsvn as it is delivered Vfrom the yarn .receivers to the reels As stated above the advantage of this is that the yarn can be twisted much vmore rapand 3; are emptied,Y

to be run olf from the drawing rolls at a` 7u greatly increased speed and the placing of the additional twist in the yarn as it is delivered from the yarn receivers of the reel 2G does 'not affect the speed at which the yarn can be handled. Therefore7 by putting 75 in the desired twist in two successive operations the output of yarn can be nearly doubled. f

It will be further noted that in all of the embodiments of the invention shown, the step of supplying the. yarn to one yarn rc ceiver for one operation- (which may be termed the creeling operation) constitutes the step of delivering the yarn from the4 next preceding operation (which may be ref ferred to as doi'ling the yarn). There lis, therefore, no separate` dotiing ofthe yarn from one operation and transferring the yarn to another machine or creeling the yarnA for the next succeeding operation. The only' exception to this is that there must bean initial creeling by hand atthe beginning of all the operations and the final dofiing from the spools 26 must be done by hand, but all the intermediate dofting and creeling operao tions are performed without removing the yarn receiver from the machine. While I have illustrated herein some selected embodiments of my invention I do not wish to be limited to theconstructional details shown. l l-laving fnlly described lmy invention, what l claim as new and desire to secure Aby Letters Patent is z- 1. In a device of the. class described, the

combination with a plurality of `sets of. drawing rolls, of a plurality of sets of drums or spools, said sets of drawing rolls and sets of drums or spools being alternately arranged, a Aplurality ofsets of yarn receivers, and means to shift the relative position of the yarn receivers and the drawing rolls and spools, the alternate sets of yarn receivers .being situated in one relative. position to re-A ceive yarn from the drawing rolls, and the other sets of yarn receivers being situated to deliver yarn to'the spools or drums, and in another relative position the first-named sets, of yarn receivers being adapted to deliver l yarn to 'the spools or drums, and the other 12o yarn receivers being adapted to receive yarn from the` drawing rolls.

2. Ina device of the class described, the combination with two sets of yarn receiv ers, drawing rolls cooperating with the yarn receivers or" one set, spools cooperating with the yarn receivers of the other set, means assoeiated with each of the yarn receivers of the first-named set to twist the yarn delivered thereto and to built up a yarn mass 13o therein, the yarn from the yarn receivers of the other set being delivered to the spools and wound thereon, said yarn receivers and the spinning rolls beinnr movable relative to each other whereby when the yarn receivers of one set are illed and those of the other empty the spinning rolls and yarn receivers may be moved relative to each other to bring ,the empty yarn receivers into cordination with the drawing rolls and the filled yarn receivers into eordnation with the spools.

`In testimony whereof, I have signed my naine to this specification, in the presence of two subscribing Witnesses.
